Hi there, I'm Ricky from the BBC World News for Schools. It's Friday the 20th of May!
Doctors help paralysed man walk again.
The $2 billion dollar space experiment.
And the bears that are invading towns!
First, to an amazing medical breakthrough. A man paralysed from the chest down is now able to stand and move his legs, thanks to doctors in America. Baseball player Rob Summers was injured after being hit by a car 5 years ago. At the time he was told he'd never walk again...
"The moment I stood up I was in disbelief, I was amazed, I was shocked, I didn't think it would happen that fast. The doctors had anticipated maybe five years I could stand, and standing on the third day, I blew all the doctors out of the water."
Doctors applied electrical pulses along his spinal cord and he can now walk on a treadmill. But experts say we should be careful not to call this a cure. Just because it worked in one person doesn't mean it will work for others, but doctors say it does give them hope!
Next to Scotland where the race is on to rescue 100 pilot whales that have become stranded. The animals have become stuck in a loch, and appear to trying to beach themselves on its rocky foreshore. Alasdair Jack is one of the marine rescuers trying to help the animals. He says pilot whales are very sociable, and if one beached it would be difficult to stop the rest from following suit...
CLIP: "When one of them becomes sick or injured their family members will not leave them. They come ashore to die basically and they will just follow suit and come straight in after them."
Now, astronauts have kick started a $2 billion dollar physics experiment in space. Earlier they set of on a spacewalk to install the main peace of kit, it's called an Alpha Magnetic Spectrometer....

The gadget is being placed on top of the International Space Station. The idea is that by analysing high energy particles, it will be able to tell us more about how the universe began!
And finally, to the bears that are causing a bit of a problem in Slovakia. It seems efforts to protect the animals have been so successful that not only are their numbers growing, but they're taking over more space - even moving into towns!....Graham Bishop is from Project Bear. Graham and his team are taking some pretty risky action to track the bears' movements ...
CLIP: "We sedate the bear using a low power gas rifle. We approach the bear, make sure it is asleep, put the collar on. We're using GPS collars so that we can see exactly what they're doing through the night, through the day. You have to work quite quickly because the drugs aren't fail-safe and there've been a number of cases worldwide where bears have woken up."
They reckon if they know what's attracting them to the towns in the first place, they might be able to figure out how to stop them.
Just before we go we have the answer to yesterday's question. We asked you what dinosaur is famous for its long neck and tail? And the answer is...the Diplodocus!
OK, that's all from the World News for Schools team but fear not, we're back next week.
